Hi,
I am trying to make a switch using IR as the trigger, when the beam between the IR LED and the reciever is broken, the switch is activated. But I seem to be stuck right at the start, I have been given a load of IR recievers ( work ordered wrong part number, lucky me ). They are from RS order number: 654-8930. I have looked at the data sheet to try to figure out how to use them, but the bit that is confusing me most is the 38Khz carrier frequency it uses.
1. Can I use a normal IR LED to transmit ro it?
2. Does the 38Khz mean I have to make a special ciruit for the reciever to work?
I have tried to search the net and this web site, but cant seem to find the answers I need.
If anyone could help that would be great.
cheers.
